Would it be possible to implement some sort of attribute in Landscape mode that would allow us to control the vertex count “with minimum shape changes” (https://www.blender.org/manual/modeling/modifiers/generate/decimate.html), such as ‘ratio’ does in decimate modifier in Blender? This would help tremendously when attempting to create low-poly terrain. I best I am able to achieve through the cross-product trick is this:
Unfortunately, this is sorta a one trick-pony. He can do spiky terrain nicely, but that is about it. Hills do not look good using this because of the amount of vertexes being used. For now I am only using it as a base layer for the map and using static meshes over it to achieve to overall look I am going for, but it would be nice if the landscape could be a tad bit more flexible. With that being said, UE4 is love, UE4 is life.
